Here are some more pics of the giant cave we visited in Halong Bay. You can see the “surprise,” illuminated in pink, about 3 photos in.
Our guide pointed out lots of rock formations within the cave that looked like something – a turtle, a laughing Buddha, etc. Mostly, though, they were of a… particular nature. A couple making love, a giant penis, a Buddha with a giant penis, etc etc. Seems like the Northern fighters who named the rocks weren’t only concerned with war.
